checking for a hard register !!

[Naveen Sharma, Noida]

Hi,

Is it all right to replace all tests of the
of the form

      (REG_NO) < FIRST_PSEUDO_REGISTER
by 
       HARD_REGISTER_P (REG_NO)  (defined in rtl.h already)

It would have two advantages
1. More readable.
2. If the perception of what a "hard reg" is changes in future
   it would be easy to incorporate the semantics.

Best Regards,
  Naveen Sharma.
